Renesas Introduces New MOSFETs
(Wireless News Via Acquire Media NewsEdge)
Renesas Technology America has introduced two new high-frequency power
MOSFETs: the RQA0010 and RQA0014 transistors for use in the transmitter
power amplifiers of handheld wireless products, including those that
combine communication, information and multimedia capabilities.
According to company officials, in typical applications, the MOSFETs
are used in tandem to amplify, to the nominal power level needed for
driving the transmission antenna and audio signals that have converted
to the high frequencies of the wireless network. They are suitable for
frequencies in the 175MHz and 500MHz bands for commercial wireless
systems, and in the 800MHz and 900MHz bands for cell phones.
Renesas noted it has achieved a 60 percent power-added efficiency (PAE)
in the RQA0010 MOSFET at 3.6V, and a 55 percent PAE in the RQA0014
MOSFET at the same supply voltage. As a result, a two-stage amplifier
that uses an RQA0010 to boost the output of an RQA0014, achieves the
industry's highest level of performance: a 1.2W output at 3.6V.
According to the company, the package used for the RQA0010 and RQA0014
MOSFETs is the proven Renesas UPAK (Renesas package code) miniature
package that measures only 4.5 x 2.5 x 1.5mm (max). It facilitates
miniaturization and thinner form factors in compact handheld wireless
products. The UPAK is a source-flange type package that combines
electrical grounding with high thermal dissipation.
Renesas Technology is a semiconductor system solution provider for
mobile, automotive and PC/AV (Audio Visual) markets.
